Question

a. 250 students wrote an exam and 18% of the students failed. Calculate the number of
students who passed the exam.
b. A purchased a car for Rs. 5,00,000, he sold the car to B for Rs. 4,50,000 calculate A’s
profit or loss percent. How much should A have sold the car for to make a profit of 20%?

Answer 1

Answer:

a) 205 students have passes

solution :

250×18/100 = 45

so, it means, 45 students have failed.

therefore, 250-45= 205 students have passed

Answer 2

Step-by-step explanation:

a) Failed students =250*18/100=45

passed students =250-45=205

b) loss =500000-450000=50000

% loss=50000/500000)*100=10%

Now

profit for 20%

500000+500000*20/100

500000+100000=600000

car should be sold =600000
